Embodiment I

Referring to FIG. 1 , FIG. 1 is a schematic structural diagram of a setof fight training equipment provided by Embodiment I of the presentdisclosure.

As shown in FIG. 1 , the fight training equipment provided by thisembodiment includes:

a training equipment body 1;

a liner 2 fixed inside the training equipment body 1;

at least one telescopic arm 4 fixed in the liner 2 through a firstelastic member 603;

a pop-up device arranged in the liner 2;

a pop-up channel matched with each arm 4 in a one-to-one correspondencemanner being arranged between the liner 2 and the training equipmentbody 1 so that the arm 4 extends from the liner 2 to the outside of thetraining equipment body 1 through the pop-up channel under the action ofthe pop-up device and the arm 4 is withdrawn to the middle part of theliner 2 through the pop-up channel under the action of the first elasticmember 603;

an arm control assembly 6 arranged on the training equipment body 1;

a drive device connected with the pop-up device;

the arm control assembly 6 being connected with the drive device andbeing used to control the drive device to drive the pop-up device.

The liner is arranged in the training equipment body; at least onetelescopic arm is arranged in the liner; the pop-up channel which ismatched with each arm in the one-to-one correspondence manner isarranged between the liner and the training equipment body so that thearm extends from the liner to the outside of the training equipment bodythrough the pop-up channel under the action of the pop-up devicearranged in the arm; the arm control assembly is further arranged on thetraining equipment body; the pop-up device or the winding device isconnected with the drive device; the drive device is connected with thearm control assembly; and the arm control assembly is used to controlthe drive device to drive the pop-up device. Based on this, the armcontrol assembly can control the drive device to drive the pop-up deviceto pop up the arm from the liner to the outside of the trainingequipment body through the pop-up channel, so as to attack people. Auser cannot predict the attack time of the arm of the fight trainingequipment of the present disclosure. Therefore, the fight trainingequipment of the present disclosure can train the reaction ability ofthe user.

It should be noted that there may be various combinations for the armcontrol assembly 6. For example, it can be formed by combining a userposition sensor and a controller, or a touch screen and a controller, ora user position sensor, a touch screen, and a controller.

When the arm control assembly includes the user position sensor and thecontroller, the user position sensor is connected with the controller.The user position sensor sends a user position signal to the controllerafter detecting a position of a user, and the controller controls,according to the user position signal, the drive device to drive thepop-up device. In this way, the arm can be controlled to be popped upaccording to the position of the user, thus improving theunpredictability of training and enhancing the training effect.

When the arm control assembly includes the touch screen and thecontroller, the touch screen is connected with the controller, and thetouch screen may detect a touch operation of the user, thus acquiring anarm attack plan. For example, the user may input attack time, an attackdirection, and the like through the touch screen to constitute the armattack plan. The touch screen sends the arm attack plan to thecontroller. The controller controls, according to the arm attack plan,the drive device to drive the pop-up device. In this way, the user maycarry out targeted training according to his own needs in a planned way,and the training effect can be enhanced.

When the arm control assembly includes the user position sensor, thetouch screen, and the controller, the user may select the user positionsensor to detect his position for training or carry out the trainingthrough the customized arm attack plan. This selection interface may beset on the touch screen, or training ways may be selected by means of aphysical switch.

In addition, based on the above arm control assembly, the equipment ofthis embodiment may further include a human motion sensor capable ofbeing in communication interaction with the controller. The human motionsensor may be worn on a trainee, i.e., user's body, and the controllermay receive a human motion signal detected by the human motion sensorand analyze the human motion, thus controlling, according to the humanmotion, the drive device to drive the pop-up device to pop up orwithdraw the arm.

In this embodiment, the fight training equipment is described in detailby taking one specific arm and the pop-up device corresponding to thearm as an example.

Referring to FIG. 2 , FIG. 2 is a schematic structural diagram of apop-up device provided by Embodiment I of the present disclosure.

The pop-up device includes a disk 3054, a first electromagnet 3062, asecond elastic member 3063, and an ejection rod 3064;

the disk 3054 is fixed on the drive device; the disk 3054 rotates underthe driving of the drive device;

the first electromagnet 3062, the second elastic member 3063, and theejection rod 3064 are fixed on the disk 3054; one end of the secondelastic member 3063 is connected with the first electromagnet 3062, andthe other end of the second elastic member is connected with a first endof the ejection rod 3064;

the arm 4 is provided with a groove matched with the ejection rod 3064;

when the first electromagnet is demagnetized, the ejection rod is poppedup by the second elastic member; a second end of the ejection rod fallsinto the groove of the arm; as the disk rotates, the ejection rod drivesthe arm to extend from the liner to the outside of the trainingequipment body through the pop-up channel;

when the first electromagnet is magnetized, the ejection rod, the secondelastic member, and the first electromagnet are attracted together, thesecond end of the ejection rod is separated from the groove, and the armretracts under the action of the first elastic member.

Specifically, an operating process of the pop-up device provided by thepresent disclosure is specifically as follows:

As the disk rotates, the disk, the first electromagnet, the secondelastic member, and the ejection rod also continuously rotate, and anorientation of the ejection rod continuously changes. Referring to FIG.2 , at this time, the arm is in a retracted state. As the disk clockwiserotates, the orientation of the ejection rod changes and faces thegroove in the arm. At this time, the first electromagnet isdemagnetized, and the ejection rod is popped up under the action of thesecond elastic member and falls into the groove. As the disk clockwiserotates, the ejection rod drives the arm to be popped up. Referring toFIG. 3 , when the first electromagnet is magnetized, the ejection rod,the second elastic member, and the first electromagnet are attractedtogether, the second end of the ejection rod is separated from thegroove. It should be noted that after the second end of the ejection rodis separated from the groove, the arm starts to be withdrawn under theaction of the first elastic member.

In addition, in the embodiment of the present disclosure, the arm mayalso bend in the pop-up process through the pop-up bending device.

In addition, there may be various kinds of drive devices. For example, afirst kind of drive device, as shown in FIGS. 4 and 5 , may include: apendulum bob 301 which swings as the fight training equipment acts, anda first ratchet wheel mechanism 302. The first ratchet wheel mechanismincludes a first ratchet wheel 3021, a first ratchet 3022, and a firstratchet fixing structure 3023 which is coaxially and rotatably fixed tothe first ratchet wheel. One end of the first ratchet is fixed on thefirst ratchet fixing mechanism, and the other end of the first ratchetpresses against any intertooth space of the first ratchet wheel. Thefirst ratchet fixing structure is fixedly connected with the pendulumbob through a swing link, so that the first ratchet fixing structurerotates as the pendulum bob swings. The drive device further includes anenergy storage structure which is in transmission connection with thefirst ratchet wheel and a power output structure connected with anoutput end of the energy storage structure. The energy storage structureis used to store mechanical energy generated by the rotation of thefirst ratchet wheel and output the stored mechanical energy to the poweroutput structure. The power output structure is connected with arotatable fixing member, so as to drive the rotatable fixing member.

When the fight training equipment acts with a force applied by a user,the pendulum bob will swing with this action, thus driving the firstratchet fixing structure to rotate. Since one end of the first ratchetis fixed on the first ratchet fixing structure, and the other endpresses against any intertooth space of the first ratchet wheel, whenthe first ratchet fixing structure rotates, the end of the first ratchetpressing against any intertooth space of the first ratchet wheel maypush the first ratchet wheel to rotate. The energy storage structure isin transmission connection with the first ratchet wheel, so that theenergy storage structure may store the mechanical energy of the rotationof the first ratchet wheel for outputting and providing power.

Further, as shown in FIGS. 6 and 7 , the first drive device may furtherinclude a first bevel gear 306, a second bevel gear 307, a third bevelgear 308, and a second ratchet wheel mechanism 309. The second ratchetwheel mechanism includes a second ratchet wheel 3091, a second ratchet3092, and a second ratchet fixing structure 3093 which is coaxially androtatably fixed to the second ratchet wheel. One end of the secondratchet is fixed on the second ratchet fixing mechanism, and the otherend of the second ratchet presses against any intertooth space of thesecond ratchet wheel. The second ratchet fixing structure is fixedlyconnected with the pendulum bob through a swing link, so that the secondratchet fixing structure rotates as the pendulum bob swings. The firstbevel gear and the first ratchet wheel are disposed in a synchronoustransmission manner, and the second bevel gear and the second ratchetwheel are disposed in a synchronous transmission manner. The first bevelgear and the second bevel gear are engaged with the third bevel gear, sothat the first bevel gear rotates to drive, through the third bevelgear, the second bevel gear to rotate according to a rotation directionopposite to that of the first bevel gear. A direction where the firstratchet pushes the first ratchet wheel is opposite to a direction wherethe second ratchet pushes the second ratchet wheel.

It should be noted that the swing of the pendulum bob has twodirections: “forward” and “backward”. In this embodiment, the swingdirection of the pendulum bob is described as a first direction and asecond direction.

When the user applies a force to enable the motion equipment to move,the pendulum bob may swing with it. When the pendulum bob swings towardsthe first direction, the first ratchet fixing structure and the secondratchet fixing structure may rotate towards the same direction with thependulum bob, and at this time, the first ratchet may push the firstratchet wheel to rotate, thus storing the mechanical energy generated bythe rotation of the first ratchet wheel in the energy storage structure.Since the direction where the first ratchet pushes the first ratchetwheel is opposite to the direction where the second ratchet pushes thesecond ratchet wheel, when the first ratchet pushes the first ratchetwheel, the second ratchet slips on the second ratchet wheel and will notpush the second ratchet wheel to rotate.

When the pendulum bob swings towards the second direction, the firstratchet fixing structure and the second ratchet fixing structure mayrotate towards the same direction with the pendulum bob, and at thistime, the second ratchet pushes the second ratchet wheel to rotate, andthe first ratchet slips on the first ratchet wheel. Since the secondbevel gear and the second ratchet wheel are disposed in the synchronoustransmission manner, when the second ratchet wheel rotates, the secondbevel gear may be synchronously driven to rotate, thus driving the thirdbevel gear engaged with the second bevel gear to rotate and furtherdriving the first bevel gear engaged with the third bevel gear to rotatealong a direction opposite to the rotation direction of the second bevelgear. Since the first bevel gear and the first ratchet wheel aredisposed in the synchronous transmission manner, the first ratchet wheelmay synchronously rotate with the first bevel gear. Since the rotationdirections of the first bevel gear and the second bevel gear areopposite, the rotation direction of the first ratchet wheel at this timeis still the same as that of the first ratchet wheel when the pendulumbob swings towards the first direction. At this time, the mechanicalenergy of the rotation in the same direction may still be provided tothe energy storage structure.

Therefore, no matter the pendulum bob swings in the first direction orthe second direction, the first ratchet wheel will provide themechanical energy in the same rotation direction to the energy storagestructure, thereby storing the mechanical energy of the pendulumswinging in two directions.

Based on the above structure, the mechanical energy in the energystorage structure will increase to provide power as long as the usermakes the training equipment act. Even in an environment where power isnot available, the sports equipment can still rely on the mechanicalenergy in the energy storage structure to give feedback to the user,allowing the user to complete the training.

The energy storage structure may be, but is not limited to, a remontoirbox. An input end 3041 of the remontoir box is in transmissionconnection with the first ratchet wheel, and an output end 3042 of theremontoir box is connected with the power output device. Thetransmission connection may be realized through a transmission gear3044.

In addition, both the input end and the output end are gears. Theremontoir box further includes a remontoir 3043. One end of theremontoir is fixedly connected with the input end, and the other end ofthe remontoir is fixedly connected with the output end.

Further, the remontoir box further includes a third ratchet 3045 and afourth ratchet 3046. One end of the third ratchet is fixed, and theother end presses against any intertooth space of the input end gear;one end of the fourth ratchet is fixed, and the other end pressesagainst any intertooth space of the output end gear.

Since the remontoir is continuously wound up, in order to prevent themechanical energy stored in the remontoir from being output from theinput end gear, the input end is provided with the third ratchet. Therotation direction of the input end gear of the wound-up remontoir ispresented as clockwise rotation. Due to the presence of the thirdratchet, the input end gear will not anticlockwise rotate, and themechanical energy in the remontoir can only be output from the outputend gear. The fourth ratchet is also to prevent the output end gear fromrotating according to a direction opposite to a preset rotationdirection.

It should be noted that the remontoir box further includes a torquelimiter 3047 arranged on an outer side of the remontoir. Since theremontoir has a certain limit, after the torque limiter is arranged onthe outer side of the remontoir, when the remontoir is wound up toexceed a torque of the torque limiter, the torque limiter will slip. Atthis time, the remontoir may not be continuously wound up, which avoidsa phenomenon of breakage of the remontoir.

The power output structure of this embodiment may include a speed changedevice, a power output gear 3051, a brake 3052, and at least oneelectromagnetic clutch 3053. The speed change device is in transmissionconnection with the output end; the power output gear is in transmissionconnection with the speed change device; and the brake and eachelectromagnetic clutch are fixed on an output shaft of the power outputgear. The speed change device, the brake, and the electromagnetic clutchare in the existing art, and descriptions thereof are omitted here.

In addition, the drive device may further be a motor and theabove-mentioned power output structure. The motor may be a speedregulation motor, a servo motor, or a stepping motor.

In addition, the speed change device and the power output structure maybe connected with the controller, so as to control a rotation speed ofthe power output gear of the power output device and working states ofthe brake and each electromagnetic clutch.

The strength measurement sensor may be a pressure sensor or anacceleration sensor. After a measured signal is sent to the controller,the controller processes the signal, and a punching strength and apunching speed of the user may be obtained. In addition, a strengthmeasurement sensor may also be arranged on the arm, so a defendcondition of the user may be obtained.

In addition, a display may be further arranged on a stand. The displayis connected with the controller and may receive data measured, throughthe various sensors, by the controller, thus obtaining the punchingstrength, the punching speed, and the defend condition of the user. Theabove data may also be sent to a server through wireless datatransmission equipment or wired data transmission equipment. A customermay acquire the data from the server through an application program in amobile terminal such as a mobile phone or a tablet computer, so as toknow the training. The wireless transmission equipment may be WIFI, andthe wired data transmission equipment may be an optical fiber and aterminal box required by optical fiber communication.

In addition to controlling, according to the user position signaldetected by the user position sensor, the arm to extend and retract, thearm attack plan may also be customized through the application program,such as the attack time, the attack speed, and the attack frequency.

In addition, a training body of this embodiment may be hung by a hangingstructure. The hanging structure may include a base and a stand. Thebase may be fixed on the ground through a vacuum chuck or a balanceweight or a screw. The stand is fixed on the base. The stand is composedof a first supporting rod perpendicular to the ground and a secondsupporting rod forming a certain angle with the ground. The trainingequipment body may be hung on the second supporting rod through a slingchain.

It should be noted that the training equipment body may also be directlyhung on a wall or a roof through the sling chain. A surface of thetraining equipment body may be bubble leather that is used to be punchedby the user. A space between the training equipment body and the linermay be filled with foam or fine sand. The liner may be made ofnondeformable hard silica gel.

a first torsion spring 606 and a guy wire 605.

Two ends of the first torsion spring 606 are fixed on an inner surfaceof the arm 4;

one end of the guy wire 605 is connected with the liner 2, and the otherend of the guy wire is connected with an end of the first torsion spring606 away from the first elastic member 603;

when the arm 4 does not extend, the guy wire 605 is in a slack state,and the arm 4 is fixed in a straightened state by the first torsionspring 606;

when the arm 4 extends a preset distance, since the guy wire 605 has alimited length, the guy wire 605 is in the straightened state; and atthis time, the arm 4 continues to extend, and the guy wire 605 may pullthe end of the first torsion spring 606 away from the first elasticmember 603, making the first torsion spring 606 rotate to drive the arm4 to bend.

It should be noted that the bending of the arm is realized by means ofthe first torsion spring. Specifically, the pop-up bending process ofthe arm is mainly divided into two processes.

Referring to FIG. 8 , one process is before the arm extends the presetdistance, and at this time, the guy wire is in the slack state, and thearm is fixed in the straightened state by the first torsion spring.

Referring to FIG. 9 , the other process is after the arm extends thepreset distance, and at this time, the guy wire is in a tightened state.Since the guy wire has a limited length, the guy wire is in thestraightened state, and the arm continues to extend. The guy wire maypull the end of the first torsion spring away from the first elasticmember, making the first torsion spring rotate to drive the arm to bend.The arm is fixed in the straightened state by the first torsion spring.

It should be noted that when the arm extends the preset distance, theguy wire is in the straightened state, that is, the guy wire does notpull the first torsion spring, and the first torsion spring does notdeform. However, if the arm continues to extend forwards, since the guywire has the limited length, the guy wire pulls the end of the firsttorsion spring away from the first elastic member, making the firsttorsion spring rotate. When the arm is withdrawn, as the guy wire ischanged from the tightened state to the slack state, the first torsionspring is restored to the original state, thus driving the arm to bestraightened.

Referring to FIG. 10 , the other specific structure of the pop-upbending device includes:

a second electromagnet 91 and a second torsion spring;

the second electromagnet 91 is connected with the controller;

the second electromagnet 91 is fixed on an inner surface of a preset armbending position;

a shaft of the second torsion spring is fixed near the secondelectromagnet 91 on the inner surface of the arm, so that one side ofthe second torsion spring is attracted to the second electromagnet 91 bytwisting and the other side of the second torsion spring is fixed on theinner surface of the arm;

the side of the second torsion spring attracted by the secondelectromagnet 91 is hook-like; when the arm is withdrawn, the hook-likeside is driven to twist till the hook-like side is attracted by thesecond electromagnet 91.

It should be noted that the bending of the arm is realized by means ofthe second torsion spring. When the second electromagnet isdemagnetized, a side 922 of the second torsion spring attracted to thesecond electromagnet twists under an elastic force of the second torsionspring till it is fitted to the inner surface of the arm. At this time,the side 922 of the second torsion spring is farther from the secondelectromagnet than the other side 923 of the second torsion spring. Theside 922 of the second torsion spring continues to twist under theelastic force of the second torsion spring, and the side 922 of thesecond torsion spring will push the arm to rotate along the shaft of thesecond torsion spring to an initial state of the second torsion spring,and the arm twists at the same time. The arm twists from the state inFIG. 10 to the state in FIG. 11 . The initial state of the secondtorsion spring is a state where neither the side 922 of the secondtorsion spring nor the other side 923 of the second torsion spring maytwist without an external force.

In addition, the number of the pop-up bending device is at least one.Since the arm may twist around the shaft of the second torsion spring ofthe pop-up bending device, the pop-up bending device is arranged on theinner surface of a part to be bent of the arm according to a need.

Embodiment III

In this embodiment III, the power output structure is described bytaking one set of specific fight training equipment as an example.

As shown in FIG. 12 , the power output structure includes a thirdelectromagnet 3061, an electromagnetic clip 3060 fixed in the liner 2, apower output gear 3051 for driving the output device, and a brake 3052arranged on the power output gear 3051;

a groove matched with the electromagnetic clip 3060 is formed in thebrake 3052;

when the third electromagnet 3061 is magnetized, the electromagneticclip 3060 is attracted and leaves the groove in the brake 3052, and thepower output gear 3051 starts to rotate to drive the pop-up device orthe winding device to work;

when the electromagnet is demagnetized, the electromagnetic clip 3060 isspread; as the brake 3052 rotates, the electromagnetic clip 3060 entersthe groove; and when the electromagnetic clip enters the groove, thebrake 3052 is locked, and the power output gear 3051 stops rotating.

It should be noted that in the solution provided by the presentdisclosure, the disk is arranged on the power output gear. As the poweroutput gear rotates, the controller is connected to a power supplycircuit of the third electromagnet to control a power supply state ofthe third electromagnet, thus controlling the rotation of the poweroutput gear.

The user cannot predict the attack time of the arm of thefight training equipment of the present disclosure. Therefore, the fighttraining equipment of the present disclosure can train the reactionability of the user.

In this embodiment, the fight training equipment is described in detailby taking one specific arm and the winding device corresponding to thearm as an example.

Referring to FIG. 14 , FIG. 14 is a schematic structural diagram of awinding device provided by Embodiment IV of the present disclosure.

one end of the pull wire 703 is fixed on the wire spool 701, and theother end of the pull wire is connected with an end of the arm close tothe first elastic member through the pulley 702.

Specifically, an operating process of the winding device provided by thepresent disclosure is specifically as follows:

when the wire spool 701 rotates, the pull wire 703 is wound on the wirespool 701, and a tail end of the pull wire 703 pulls the arm to bewithdrawn from the outside of the training equipment body.

Referring to FIG. 15 , FIG. 15 is a schematic diagram of a first stateof one kind of winding device provided by Embodiment IV of the presentdisclosure. The first state means a state that the arm is pulled halfwayback into the training equipment body.

When the arm is withdrawn to the locking mechanism and locked, the firstelastic member is compressed; the pull wire 703 fixed on the wire spool701 slides off from the wire spool 701 under the guidance of the slopebulge 704.

Referring to FIG. 16 , FIG. 16 is a schematic diagram of a second stateof one kind of winding device provided by Embodiment IV of the presentdisclosure. The second state means a state that the arm is withdrawninto the liner.

Acone structure 705 is connected with a side of the arm 4 close to thepulley. The pull wire 703 is connected to the cone structure 705. Whenthe pull wire 703 pulls the cone structure 705 through the pulley, thearm 4 is pulled. When the cone structure is pulled to the metal rod 706,the metal rod 706 is extruded, and the springs 707 are compressed. Whenthe side of the cone structure 705 close to the arm 4 passes through themetal rod 706, the springs 707 are popped up at this time, the metal rod706 is also popped up and prevents the cone structure from movingtowards the outside of the equipment body, and the arm is locked. Themotor (not shown in the figure) is connected with the metal rod 706through another pull wire. When the motor pull wire pulls the metal rod706 down, the metal rod moves down, and at this time, the metal rod 706will no longer block the cone structure 705, and the arm 4 is released.The arm 4 moves from the liner to the outside of the equipment bodyunder the action of the first elastic member 603.
